Titanium Tube for Heat Exchangers, Chemical and Seawater Service
Titanium tube is widely evaluated for heat-transfer and corrosion-resistant equipment, but material selection must reflect the actual service, equipment design and fabrication route.
Application Questions
- Process medium, concentration and temperature
- Cooling water, seawater, chlorides and fouling
- Pressure, velocity, erosion and vibration
- Tube-to-tubesheet joint and welding procedure
- Cleaning chemistry and shutdown conditions
Product Definition
State grade, ASTM standard and revision, seamless or welded route, OD, wall, length, tolerances, condition and surface. Heat-exchanger tube orders should also define straightness, ends and eddy-current, hydrostatic or pneumatic testing as required.
Fabrication and Inspection
Tube quality alone cannot correct unsuitable tubesheet material, expansion, weld procedure, crevice design or galvanic coupling. Review the complete equipment system.
Product options: Grade 2 Seamless Tube, Grade 2 Welded Tube and Grade 7 Seamless Tube.
